BIANCHI PACKAGE Simulating Bianchi induced temperature fluctuations in CMB maps --------------------------------------------------------------- DESCRIPTION This package provides functionality to support the simulation of Bianchi Type VIIh induced temperature fluctuations in CMB maps of a universe with shear and rotation. The implementation is based on the solutions to the Bianchi models derived by Barrow et al. (1985), which do not incorporate any dark energy component. Functionality is provided to compute the induced fluctuations on the sphere directly in either real or harmonic space. VERSION Release 1.1, 1 July 2008 AUTHORS J. D. McEwen (http://www.jasonmcewen.org) ACKNOWLEDGEMENTS D. J. Mortlock M. P. Hobson A. N. Lasenby REFERENCE The BIANCHI package was written originally to determine whether recent evidence for non-Gaussianity in WMAP CMB observations were due to Bianchi contributions. The code is based on solutions to the Bianchi models derived by: Barrow J. D., Juszkiewica R., Sonoda D. H., 1985, MNRAS, 213, 917 If you use the code to produce published works please reference the download site http://www.mrao.cam.ac.uk/~jdm57/ and our related paper: J. D. McEwen, M. P. Hobson, A. N.
